The most likely image class of the document printed copy is determined using a trained meta-classifier using the estimated class probabilities. An image of the document printed copy and the most likely class of the document printed copy are then entered into the assigning tool. The most likely class determined by the trained meta-classifier is assigned by the assigning tool to the image of the document printed copy to obtain a classified image of the document printed copy.
